Water is where most beginners go wrong — usually by watering little and often, which keeps roots shallow and weak. The trick is to water deeply but less often, so roots grow down and plants cope better with dry spells. Here is how, when and how much to water.
- Deeply soak, don't sprinkle
- Less often let roots grow down
- Morning less evaporation
- At the roots keep leaves dry
How much and how often
Most established plants prefer a good soak a couple of times a week rather than a daily splash. Water until the soil is moist several centimetres down, then let the surface dry before the next round. Check by pushing a finger into the soil — if it is damp below, leave it. Sandy soil and containers dry faster; clay holds water longer.
When to water
Early morning is best: plants drink up before the heat, and leaves dry quickly, which discourages disease. Evening is second best. Avoid watering in the midday sun — much of it simply evaporates before it reaches the roots.
Seedlings and containers need care
Young seedlings have tiny roots, so water gently from below or with a fine rose and never let them dry out — but avoid sogginess, which causes damping off. Pots and containers dry out fast, especially in wind and sun, and may need daily watering in summer. See starting seeds indoors for early-stage care.
Use less water, not more
A mulch locks moisture into the soil so you water far less often. Water at the base rather than over the leaves, group thirsty plants together, and collect rainwater in a butt where you can. Improving your soil with organic matter also helps it hold water.
Over- or under-watered?
- Under-watered: wilting, dry crumbly soil, crisp leaf edges.
- Over-watered: yellowing leaves, soft growth, constantly soggy soil.
- When unsure, check the soil below the surface before reaching for the can.
Frequently asked questions
How often should I water?
There is no fixed rule — check the soil. A deep soak 2–3 times a week beats a daily sprinkle for most plants.
Should I water every day in summer?
Containers often yes; beds usually no — water deeply and let the surface dry between.
Is it bad to water in the evening?
It is fine; just try to keep the leaves dry to avoid overnight disease.
Can I overwater?
Yes — soggy soil starves roots of air and rots them. Moist, not wet, is the aim.
Water well, then browse all seeds.
